Nuclear physics techniques for determination of rocks age
The low background nuclear physics techniques were used for measure age geologic samples of micas (biotite, lepidolite, muscovite, phlogopite) by means of detection a gamma radiation from radioisotopes. The nuclear reactions ⁸⁷Sr(γ,γ`)⁸⁷mSr, ⁸⁷Rb(γ,n)⁸⁶Rb and ⁸⁵Rb(γ,n)⁸⁴Rb was used. Application of...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The low background nuclear physics techniques were used for measure age geologic samples of micas (biotite, lepidolite, muscovite, phlogopite) by means of detection a gamma radiation from radioisotopes. The nuclear reactions ⁸⁷Sr(γ,γ`)⁸⁷mSr, ⁸⁷Rb(γ,n)⁸⁶Rb and ⁸⁵Rb(γ,n)⁸⁴Rb was used. Application of a braking radiation of the powerful accelerator of electrons has allowed simultaneously to measure an element composition of samples. The age of biotite from the deposit Stankovatskoe (Ukraine) was measured that corresponds an inhering lithium pegmatites of the Kirovograd block of the Ukrainian Shield to relevant global paleoproterozoic metallogenic episode by age 2.4⋅10⁹ years. |
